Abstract

L'invention concerne un dispositif d'interruption de données qui comprend un port d'entrée, un port de sortie et une connexion entre ces deux ports. Le dispositif d'interruption de données permet de créer deux états: dans le premier, la connexion entre le port d'entrée et le port de sortie est ouverte, et dans le deuxième elle est fermée. Un interrupteur assure la transition entre ces deux états. Le dispositif comprend également un mécanisme externe, de préférence un bouton-poussoir, qui sert à activer l'interrupteur. En cas de besoin, l'interrupteur peut aussi être commandé à partir d'un ordinateur.
